no, it just means that it didn't inject the code in time. that's why they call it a race attack I think. you just have to accept that ps4 exploits are unstable. it's even somewhat unstable on 5.05, which is what I'm on. I've had kernel panics, even ones a few moments after the exploit went through. usually, the exploit runs well after that brief moment. I've never had a kp installing pkgs or running a game, but I have had them coming back from rest mode. and, remember, this is on the golden firmware on 5.05. you can't expect it to run the best.
